So a friend of mine called up yesterday asking about a problem on a 1998 Chevy Tahoe he's buying. Over it 88K career it's had five blower switches replaced. I'm gonna end up fixing it for him and will check out the blower motor for excessive draw and burnt connections and connectors. Anybody run into this problem before? Any recalls from Chevy? Five switches is pretty unusual at best! It does not have automatic air.
